Dental-related function and oral health in relation to eating performance in assisted living residents with and without cognitive impairment

Cognitive status and dental-related function in older adults seeking community-based dental care: A Pilot Study

OBJECTIVE

This study aims to understand the prevalence of cognitive impairment and dentally-related functional (DRF) loss among older adults seeking community-based dental care.

METHODS AND RESULTS

A total of 149 adults aged 65 or older who visited the University of Iowa College of Dentistry Clinics and who had no prior documented cognitive impairment were recruited in 2017 and 2018. Participants underwent a brief interview, a cognitive assessment, and an assessment of DRF. Bivariate and multivariate analyses were used to assess associations between demographic variables, DRF, and cognitive function. Close to half (40.7%) of the patients presented with some degree of cognitive impairment, and impaired DRF was observed in 13.8%. Compared to those without cognitive impairment, elderly dental patients with cognitive impairment were 15% more likely to present with impaired DRF (odds ratio = 1.15, 95% CI = (1.05, 1.26).

CONCLUSION

Cognitive impairment is likely more prevalent in older adults seeking dental care than is generally understood by providers. Given its impact on DRF, dental providers should be alert to the possible need to evaluate patients' cognitive status and DRF in order to be able to adjust treatment and recommendations accordingly.

Temporal Relationships Between Nursing Home Staff Care Approaches and Behaviors of Residents With Dementia During Mealtimes: A Sequential Analysis

Background and Objectives

Optimal dyadic interactions are critical to quality mealtime care and outcomes. Prior work supports associative relationships between staff approaches and individual mealtime behaviors, yet evidence on temporal relationships is limited. This study examined temporal associations between staff approaches and resident behaviors during mealtimes.

Research Design and Methods

Videotaped mealtime observations (N = 160) involving 36 staff and 27 residents (53 staff-resident dyads) in 9 nursing homes were analyzed. Sequential analyses using 5-, 10-, and 15-second time windows were conducted for resident positive, neutral, and challenging behaviors as antecedents as well as consequences of staff person-centered and task-centered approaches.

Results

Residents exhibited positive verbal (35.0%) and positive/neutral nonverbal (12.6%) behaviors, as well as challenging behaviors including functional impairments (27.7%) and resistive behaviors (24.7%). Staff primarily used person-centered approaches (54.1% verbal, 40.3% nonverbal); task-centered approaches were less frequent (5.6%). Immediately (within 5 seconds) after staff person-centered approaches, resident positive/neutral and resistive behaviors were more likely, and functional impairments less likely. After staff task-centered approaches, resident positive verbal and resistive behaviors were less likely. After resident positive/neutral behaviors, staff person-centered approaches were more likely. After resident functional impairments, staff person-centered verbal approaches were less likely, and task-centered approaches more likely. After resident resistive behaviors, all staff approaches were more likely. The strength of temporal relationships diminished in 10-second and 15-second time windows.

Discussion and Implications

Staff-resident positive interactions were associated with more subsequent positive interactions. Person-centered care was associated with fewer subsequent resident functional impairments and more subsequent resistive behaviors. Resident resistive behaviors were associated with more subsequent person-centered and task-centered care. Findings confirm the importance of facilitating positive staff-resident interactions and managing functional impairments using person-centered care. Resistive behaviors require additional awareness and attention beyond commonly used person-centered care approaches. Further investigation of temporal relationships is needed using larger diverse samples.

Person-centred and task-centred care: Impact on mealtime behaviours in nursing home residents with dementia

INTRODUCTION

Mealtime is a critical daily activity to ensure nutrition, hydration, function and socialisation. Interactions between staff and residents during mealtimes are complex and dynamic processes including verbal and/or nonverbal communication that can be positive/neutral or challenging. This study examined characteristics of and relationships between person-centred and task-centred care and positive/neutral and challenging mealtime behaviours in persons with dementia.

METHODS

This study was a secondary behavioural analyses of videotaped mealtime observations (n = 110) involving 42 unique staff-resident dyads (29 staff and 25 residents with dementia) in nine nursing homes. The refined Cue Utilization and Engagement in Dementia mealtime video-coding scheme was used to code videos during 2019-2020. Dependent variables representing resident mealtime behaviours included positive verbal behaviours, positive/neutral nonverbal behaviours, functional impairments (nonverbal) and resistive behaviours (verbal and nonverbal). Independent variables were staff person-centred and task-centred approaches (verbal and nonverbal). Relationships between resident mealtime behaviours and staff approaches were examined using bivariate analysis and logistic regression.

RESULTS

Staff person-centred verbal approaches were associated with resident positive verbal behaviours (OR = 1.38, 95% CI = 1.09-1.76), functional impairments (OR = 0.81, 95% CI = 0.66-1.00) and resistive behaviours (OR = 1.65, 95% CI = 1.18-2.31). Staff person-centred nonverbal approaches were associated with resident functional impairments (OR = 1.33, 95% CI = 1.02-1.74). Staff task-centred approaches were not associated with resident positive/neutral or challenging mealtime behaviours.

CONCLUSION

This study characterised staff approaches and resident behaviours during mealtime care and provided preliminary support on associations between staff person-centred approaches and resident positive and challenging behaviours. Person-centred mealtime care practice is recommended by focusing on support of common, challenging behaviours and reinforcement of positive behaviours with adequate consideration of individual needs and preferences.

Food intake is associated with verbal interactions between nursing home staff and residents with dementia: A secondary analysis of videotaped observations

BACKGROUND

Nursing home residents with dementia commonly experience low food intake, leading to negative functional and nutritional consequences. While the importance of staff-resident (dyadic) interactions during mealtime is acknowledged, little research has examined the role of dyadic verbal interactions on food intake.

OBJECTIVES

This study aimed to examine the relationship between food intake and dyadic verbal interactions.

METHODS

This study was a secondary analysis of 110 videotaped observations of mealtime care interactions among 25 residents with dementia and 29 staff (42 unique dyads) in 9 nursing homes. Staff positive utterances and resident positive and negative utterances (independent variables) and food intake (dependent variable) were coded from the videotaped observations using the Cue Utilization and Engagement in Dementia video coding scheme. A linear mixed model was fit to the data. The two-way interaction effects of food type and video duration with each independent variable as well as two-way interaction effects among the independent variables were tested. Covariates included in the model were the number of years staff worked as a caregiver, and resident age, gender, and eating function.

RESULTS

The model included three significant interaction effects involving verbal variables: the interaction effect of staff positive utterances with resident positive utterances (p=.030), the interaction effect of staff positive utterances with food type (p=.027), and the interaction effect of resident negative utterances with video duration (p=0.002). Increased number of intakes of liquid food per minute was associated with increased number of staff positive utterances per minute when residents did not make positive utterances. Decreased number of intakes of solid food per minute was associated with increased number of staff positive utterances per minute, especially when residents made between 0 and 3 positive utterances per minute. As the duration of the videos increased, the number of intakes per minute increased for residents who made one or more negative utterances and decreased for residents who made no negative utterances in the videos. The number of intakes per minute was associated with resident gender in that male residents had increased number of intakes per minute compared with female residents (p=.017), and was not associated with other participant characteristics.

CONCLUSION

Intake was associated with dyadic verbal interactions, and such relationship was complex in that it was moderated by food type and video duration. Findings support the significant role of dyadic verbal interactions on intake, and inform the development of effective, tailored mealtime care interventions to promote intake.

Eating performance in relation to intake of solid and liquid food in nursing home residents with dementia: A secondary behavioral analysis of mealtime videos

BACKGROUND

Persons with dementia commonly experience low food intake leading to negative nutritional and functional outcomes. While multilevel personal and environmental factors that influence intake are implicated, evidence is lacking on the role of characteristics of dynamic eating performance cycles. An eating performance cycle is defined as the process of getting food from the plate or container, transporting it into the mouth, and chewing and swallowing it.

OBJECTIVE

This study aimed to examine the association between intake and characteristics of eating performance cycles among nursing home residents with dementia.

METHODS

A secondary analysis of 111 mealtime video clips from a nursing home communication training study was conducted. The 111 videos involved 25 residents and 29 staff (N = 42 unique staff-resident dyads) in 9 nursing homes. The Cue Utilization and Engagement in Dementia Mealtime video-coding scheme was used to code the characteristics of eating performance cycles, including eating technique (resident-completed, staff-facilitated), type of food (solid, liquid), duration of each eating performance cycle, and intake outcome (intake, no intake). The Generalized Linear Mixed Model was used to examine the interaction effects of eating technique by type of food, eating technique by duration, and type of food by duration on intake outcome.

RESULTS

Totally 1122 eating performance cycles were coded from 111 video clips. The majority of the cycles (85.7%) resulted in intake. There were significant interactions for eating technique by duration, and type of food by duration. As the duration of the eating performance cycle increased, staff-facilitated cycles resulted in greater odds of intake than resident-completed cycles (OR = 17.80 vs. 2.73); and cycles involving liquid food resulted in greater odds of intake than cycles involving solid food (OR = 15.42 vs. 3.15). Though the interaction between eating technique and type of food was not significant, the odds of intake were greater for resident-completed cycles than for staff-facilitated cycles regardless of the type of food being involved in the cycle (OR = 3.60 for liquid food, OR = 10.69 for solid food).

CONCLUSIONS

The findings pointed out the importance of supporting resident independence in eating performance, providing liquid food when residents struggle with solid food, and provision of longer and continuous facilitation at mealtimes to improve intake. The findings inform the development and implementation of innovative mealtime assistance and staff training to promote eating performance and intake.
